SPECIFICATION forming part of Letters Patent No. 761,000, dated May 24, 1904. Application filed November 7, 1903. Serial'No. 180,192. (No model.)

zen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Trolley, of which the following is a full, clear, and exact description.

This invention relates to improvements in trolleys used in connection with overhead wires of electric railways, an object being to provide a simple and novel means for preventing the accidental displacement of the trolley from the wire.

I will describe a trolley embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a trolley with a retaining device embodying my invention attached thereto and in closed position. Fig. 2 is a similar view, but showing themtaining-jaws as open; and Fig. 3 is a plan view. Referring to the drawings, 1 designates a trolley-pole, in the fork of which is an ordi nary trolley 2, mounted on a spindle 3, which has its ends projected outward from the fork members. The retaining device consists of two jaws 4 5, the said jaws being mounted to swing on the projected ends of the spindle 3. The jaws are provided with openings sufliciently large to permit the spindle to pass loosely through, and pins 6 extend through the spindle at the outer sides of the jaws, preventing the said jaws from slipping ofi the ends of the spindle. The upper portions of the jaws are curved inward, so as to meet directly over the trolley and wire, as indicated in Fig. 1. The downwardly-projected portions of the jaws are provided with openings 7, through which a bar 8 passes, the said bar being provided with pins 9 at the outer ends to prevent the detachment of the jaws from the bar. Attached to the bar between the jaws is a col lar 10, and between the collar 10 and the jaw 4 is a spring 11, while a similar spring 12 is placed between said collar and the jaw 5. These springs serve to separate the lower portions of the jaws, and consequently close the upper portions.

A trolley-rope 13 has connections 14. 15 with the lower ends of the jaws. Each jaw has a spring connection 16 with the trolley-pole. These springs 16 serve to hold the jaws yieldingly in a substantially vertical position.

When it is desired to place the trolley on a wire or to remove it therefrom, it is only necessary to draw downward on the rope connection 14:, when the jaws will be spread apart, as indicated in Fig. 2. After placing the trolley on the wire and releasing the rope the said jaws will move together, as indicated in Fig. 1. The jaws when closed are sufiiciently close to the trolley to prevent the wire from slipping between the trolley and the jaws.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a trolley, of jaws mounted to swing on opposite sides thereof and adapted to meet at their upper ends above the trolley, a rod with which the lower ends of the jaws have sliding connection, and

springs surrounding said rod for moving the upper ends of the jaws together.

2. The'combination with a trolley-pole and a trolley, of a trolley-spindle having its ends projected outward from the fork of the trolley-pole, curved jaws mounted to swing on said projected ends, the lower portions of the jaws being provided with holes, a bar passing JAMES A. LAVERY.
